CGI stands for Computer Generated Image. The term is often used when discussing things like; Animation, 3D models, visual effects added to a movie. An example of VFX is the flying of Tony Starks Iron Man in The Avengers. Although CGI is generated by a computer, it is often a combination of Artist and Computer which creates brilliant imagery. It is for this reason that CGI takes a vastly long time to generate.
As of late, CGI has been replaced with Real-Time Visualisations. At Scenegraph, we utilise the tool in the industry for real time visualisation – Epic’s Unreal Engine.
We also use a combination of open-source (free) tools to greatly reduce costs for our clients.
